The easily transportable Lagoon Crawler from Nuhn Industries helps agitate lagoons, creating a mix that can provide a higher concentration of nutrients in the manure and increase crop yield. It can pump 10,000 gpm and is remote controlled to a distance of 1,000 feet. It has a triple port header pump and a 6-inch front agitation canon that allow it to pump thick manure and crush through thick crusts. It blasts away sand and soil buildup, increasing storage, and it eliminates the expense of additional clean-out once the lagoon has been pumped. The four-wheel-drive system makes it flexible. If the unit gets caught up on solid buildup, it can drop its large aggressive tread tires to drive itself out. It can also drive out of the lagoon when the job is done. 877/837-7323; www.nuhn.ca.
